Q: I want to post a realistic sketch, but am such a bad artist that my friends think it looks like some sort of futuristic space vehicle. I still named it "Portrait of Shiina Ringo".
A: If the sketch constitutes a portrait of Sheena Ringo, posting it would be considered unauthorized use of her portrait. The same holds true for a sketch-like illustration or a somewhat out-of-focus photo. Sketches that bear no resemblance to Sheena Ringo are fine, though these would not be considered sketches of Sheena Ringo per se. Thank you for your understanding.
